PAPER-FASTENER Specification of Letters Patent.

Patented Dec. 28, iaao.

Application filed February 25, 1920; Serial No. 361,130.;

To all whom it may concern:

Be it known that I, FRED J. Kaine, a citizen of the United States, and aresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Paper- Fa'steners,of which the following is a specification.

This invention relates to paper fasteners and particularly to that typeof paper fastener disclosed in my co-pending application, Serial No.342,421, filed Dec. 4, 1919, and which type of fastener embodies amember having a base portion and two spaced apart tongues, and aretaining member having two slots through which the tongues can bepassed and then bent down flat-on the top surface of said member.

The main object of my present invention is to provide improved means forshielding or guarding the tongues and preventing them from catchingloose papers after they have been passed through a file of papers andthe retaining member and bent flat'on the latter. 7

My improvements relate particularly to means for quick application andremoval of the tongue-shielding means, and especially to providing suchmeans as are of easy and convenient manipulation.

The means I prefer to use for accomplishing the above objects togetherwith other features of my invention, are illustrated in the drawingaccompanying and forming part of this specification, and in which Figure1 of the drawing is a plan of the preferred form of my improved paperfastener, showing the tongue-shielding member in process of application.

Fig. 2 is a plan showing the fastener with the tongue-shielding memberin its final position on the fastener.

Fig. 3 is'a section on the line 33 of Fig. 2.

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 is a plan of the tongue-shielding member.

Fig. 6 is a partial front elevation of the tongue-shielding member.

Fig. 7 is a plan of a modified form of the tongue-shielding member.

Fig. 8 is a plan of another modification of the tongueshielding member.

Like characters of reference refer to like parts in all the figures ofthe drawing.

The first four figures of the drawing illustrate my improved paperfastener applied to a file F of papers, documents or the like. Thefastener consists of a member 2 having two tongues 3 spaced apart, oneat each end, which tongues are capable of being pushed through the fileof papers F and through a retaining member 4 provided with perforations5 through which the tongues are passed. The tongues 33 are then bentflat on the top of the retaining member 4 as illustrated in Figs. 3 and4.

The tongues?) when thus bent down are shielded or guarded from catchingon loose papers by a tongue-shielding or covering member 6 which may beof any suitable form, but in this instance is made in the form of a flatrectangular piece of sheet metal preferably as illustrated in Fig. 5.

For securing the tongue-shielding or covering member 6, suitable meansare provided such as projections adapted to hold the said member, andare preferably arranged 1n two rows, one row on each side of the member4. The projections may be of any suitable form such as the lugs or hooks9 whose overhanging portions 9 face inward, sothat the member 6 can beslid endwise under them.

To provide for quick and easy applica- 35 tion of the member 6, Iprovide slots such as 20 in one of the longitudinal edges of the member6 and these slots register with the projections or hooks 9 on one sideof the member 4.

To apply the covering member 6, it is first placed with its lower edge21 under the lower row of hooks of the member 4 with the slots 20registering with the upper hooks. It is then pushed down to the positionshown in Fig. 1, after which it is slid endwise into the position shownin Fig. 2, and the tongues are then eifectivelv guarded or shielded andcannot catch on papers and other objects.

I also provide means for locking the tongue-shielding or covering member6 in the position shown in Fig. 2, and said means are formed by makingtwo slits 23 in the metal of the edge portion 21 and slightly raisingthe portions 24 beside the slits. When the member 6 is moved from theposition of Fig. 1 to that of Fig. 2, the right hand portion 24 slipsunder the projection 9 and when it reaches the position of Fig. 2, themiddle of the member 6 springs upward, and both of the portions 24project up sufficiently to prevent further endwise movement of themember 6.

In the modification illustrated in Fig; 7

the slots are placed on both sides of the tongue-shielding member 6, andfor placing the member 6 in position, it is first slipped down over thehooks 9 and then it is slid lengthwise until the wider portions 22 areunder the hooks or projections 9.

The modification shown in Fig; 8 is of the same construction andoperation as the form shown in Figs. 1 to 4 inclusive except in themeans for locking the member 6 in position. A shallow slot 25 isprovided in the edge portion 21 of the member 6, and when the saidmember is in the position shown in Fig. 2, a slight lateralmovement ofthe member 6 looks the shoulders 26 against the upright portions oflower middle hook or projection 9.

What I claim is 1. A paper fastener comprising a portion having spacedapart tongues, a retaining member having tongue-shieldholdingproe'ctions and having slots through which the tongues can be passed andthen bent flat on said member, and a tongue shield having side slotsarranged to register with the projections, said shield being adapted toslide endwise and be held under the projections.

2. A paper fastener comprising a portion having spaced apart tongues, aretaining member having tongue-shield hooks and having slots throughwhich the tongues can be passed and then bent flat on said member, and atongue-shield having side slots arranged to register with the hooks,said shield being adapted to slide so as to be held under said hooks.

3. A paper fastener comprising a portion having spaced apart tongues, aretaining member having slots for said tongues and tongue-shield hookson each side, and a tongue-shield having slots on one side registeringwith the hooks on that side, and adapted to be held by the hooks on theopposite side, and to slide under and be held by the hooks on theslotted side.

A. A paper fastener comprising a portion having spaced apart tongues, aretaining member having tongue-shield-holding projections and having twoslots through which the tongues can'be passed and then bent fiat on saidmember, and a tongue-shield having side slots arranged to register withthe projections, said shield being adapted to slide endwise and be heldunder said proj ections, and having means for locking it in its finalposition.

5. A paper fastener comprising a portion having spaced apart tongues, aretaining member having two slots for said tongues and tongue-shieldhooks on each side, and a tongue-shield having slots on one sideregistering with the hooks on that side and adapted to be held under thehooks on the opposite side, to slide endwise and be held under the hookson the slotted side, and provided with means for locking it under saidhooks.
